If the devs work it out alright, then I’d certainly like to welcome planes and ships.
– Ships shouldn’t be a big problem of influence to the game, though they will need to make the standard rivers broader then they now are imo.
– I can understand that people are a holding back to the idea of adding planes, this will influence the game far more then ships. The whole economy will need to be rebalanced. Also the map sizes are a discussion if they are suited/big enough to carry planes.
– The main focus is and must be trains, I actually would like to see far more train engines and mod packs. I personally hope to see a dutch NS trainset which you also had for oTTD and Locomotion.
Still I would like to welcome planes and boats, aslong as the devs do it right. Planes felt a bit like cheating in Transport Tycoon to me.
